Specification of Letters Patent.

Application filed August 26, 1905. Serial No.27as69.

I Patented June 19,

To all whom it'mwy cancer-Inf Be it known that I, FREDERIOK DRISSLER, acitizen of the United States, residing at New York, in the county ofNewYork and State New York, have invented certain new and usefulImprovements in Safety-Locks for Brooches, Scarf-Pins, and the Like, ofwhich the following is a specification, such aswill enable those skilledin the art to which it appertains to make and use the same.

This inventionrelates to brooches; scarfpins, and other devices of thisclass; and the object thereof is to provide a pin of this class with asafety lock or attachment whereby when the lock or attachment is in usethe pin cannot be accidentally or otherwise detached; and with this andother objects in view the invention consists in a device of the classspecified constructed as hereinafter described and claimed.

The invention is fully'disclosed in the following specification, ofwhich the accompanying drawings form a part, in which the separate partsof my improvement are designated by suitable reference characters ineach of the views and in which I Figure 1 is a side view of an ordinarybrooch-pin provided with my improvement;

'Fig. 2, anend view looking in the direction of the arrow 00 of Fig. 1Fig.3, a section on the line 3 3 of Fig. 1; Fig. 4, an enlarged viewsimilar to Fig. 2, but showing the lock in a different position; Fig. 5,a side view of the device 'as shown in Fig. 4; and Fig. 6 a view similarto Fig. 3, but showing the lock in a different position, and in theaccompanying drawin s Figs. 4 to 6, inclusive, are on a scale lar er tan Figs. -1 to 3, inclusive.

n the drawings forming part of this specification I have shown at a themain part of an ordinary brooch, and said main art is pro, vided at oneend and at the back t ereof with a stud a to which is pivoted a pin b,and the main part a of the brooch is provided at the opposite end or atthe back thereof with a stud a having a hook memberafi, which thepointed end 0 the pin 1) is adapted to engage through an opening a inthe usual manner and as shown in Figs. 1, 2, and 3, and the stud a formsthe base of the hook a Pivoted in the stud a? is a hook-arm c, having ashank 0 which asses through said stud, as clearly indicated Figs. 1, 3,and 5 and the shank c is provided at the end oppo ,site the hook-arm cwith a lock-finger 0 The pointed end of the pin 1) and which the hookarm0 is adapted to engage when the lock is n operation, as clearlyindicatedin Figs. 2 an 3. The radius of the arc of movement of the freeend of the hook-arm c is less than the dis tance between the lug orprojection a and the point where the shank c of said arm pa through thestud a and'the free end 0 of he hook-arm c, which constitutes a part ofthe locking device, is curved upwardly and is adapted to pass over thelug or projection a when said hook-arm is in its operative position, andthe hook a is also made slightly jectiona, which extends parallel withth elastic or resilient, so that the free end thereof "tion shown inFigs. 1 to 3, inclusive, the finger 0 which constitutes a part of thelock, will be thrown into the position shown in Figs 2 and 3,. andtheend thereof will be thrown approximately into enga ement with the freeend of the hook a, as s own at d in Figs. 2 and 3.

In practice the pin 1) is passed through the material with which it isdesired to connect the pin or brooch and is engaged with the hook a, asshown in Figs. 1 to 3, inclusive. In this operation the hook-arm c is inthe position shown in Figs. 4 and 6. After the pin 6 has been engagedwith the hook a as shown in Fi s. 2 and 3, the hook-arm 0 is forcedforward y into the position shown in Figs. 2 and 3, and thissubstantially closes the opening at 0 made by the-hook a and throughwhich the pointed end of the pin is passed into said hook, and when theparts are in this osi tion the pin 7) cannot be detached from t e hookat and the brooch will remain securely at tached to the garmentorarticle to which it is applied or to which it is secured. In order torelease the in b from the hook a, thehookarm 0 must e forced backwardlyinto the po IIO locking=arm c, completes the loop formed by the hookmember c.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is

In a device of the class described, a loopshaped hook member open at oneside and adapted to receive the pointed end of a pin, a locking-armpivoted in the base of the hook member by means of a shank connectedtherewith and passing through said base, said shank being provided onthe side of the baseof the hook member opposite the locking-arm with alocking-finger adapted to be thrown into approximate engagement with theend of the hook member so as to complete the loop formed thereby, andmeans whereby the lockin -arm may be engaged with the hook member whensaid arm and finger are in their operative positions, substantially asshown and described.

In testimony that I claim the foregoing as my invention Ihave signed myname, in presence of the subscribing Witnesses, this 25th day of August,1905.

FREDERICK DRISSLER.
